Unexpected problem occurred while trying to perform a Full-Text search

SYMPTOMS

An end-user receives the following error message in Legal Review while performing a full-text search:

"An unexpected problem occurred while we were trying to perform a full-text search.  It could happen because the search index is too large and the server is too busy to handle the request.  Please try again in a little while or refine the query.  If the error still occurs, please contact your system administrator."

End-user receives the following error message in ZyFind when trying to perform the same Full-Text search:

"The following error occurred while opening index (folder path): TBIE: Error opening index, is your ZyLAB Information Management Service running?"

CAUSE

The 'IndexFolder' location value in the 'ZyLAB.Platform.WinService.exe.config' file on offending server has been changed to a value that was not valid for that server.

RESOLUTION

Edit the 'ZyLAB.Platform.WinService.exe.config' file located in the '\Program Files\ZyLAB\Information Management Platform\Services\Bin' folder.
Locate and edit the following value in the 'ZyLAB.Platform.WinService.exe.config' file to the correct location of the TBIE Indexes folder:

    <add key="IndexFolder" value=".\ZyLAB Data\TBIE Indexes" />

Restart the Information Management Service on the server after the value is corrected, then perform a Full-Text search.
